Re: [rules-users] newbie, Expressing a rule in different ways

Can you please explain why the second form of the same (as it seems to me) rule does not work? This works: rule "takeTwo"  when    $c : CD713AType( Body.incrementalUpdateOfEconomicOperators.traderAuthorisation.size != 0 )    $t : TraderAuthorisationType ( $t.OperatorRole.size == 0) from $c.Body.incrementalUpdateOfEconomicOperators.traderAuthorisation  then    stdout(drools.getRule().getName()+" "+$c.getHeader().getMessageIdentifier()); end and this fails to compile: rule "take3"  when    $c : CD713AType( $i : this.Body.incrementalUpdateOfEconomicOperators )    $t : TraderAuthorisationType ( $t.OperatorRole.size !=0 ) from $i.traderAuthorisation  then    stdout(drools.getRule().getName()+" "+$c.getHeader().getMessageIdentifier()); end with the message: Unable to build expression for 'from' : Failed to compile: 1 compilation error(s):  - (1,22) unqualified type in strict mode for: traderAuthorisation '$i.traderAuthorisation' : [Rule name='take3'] Pretty new to Drools and try to figure out how things work. In the second form of the rule I am trying to use the $i variable as a shortcut for the "Body.incrementalUpdateOfEconomicOperators" locator. "stdout" is just a function that print to System.out Thank you for your time, -Stathis _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
